| 摘 要： | 筲箕湾铅锌矿床是近年在川一滇一黔铅锌成矿域黔西北铅锌成矿区垭都一蟒硐成矿带发现的中型矿床，有关其地质、地球化学研究前人极少涉及，严重制约了成矿机制和成矿预测研究。本次工作对该矿床原生矿体主要矿石矿物（黄铁矿、方铅矿和闪锌矿）进行了硫同位素组成分析，探讨了成矿流体中硫的来源。结果表明，矿床 δ34s值集中在10％。～12％e之间，不同于δ34S值在O‰附近的幔源硫，与区域各时代碳酸盐岩地层中石膏、重晶石等硫酸盐矿物的δ34s值（约15％o）相近，认为成矿流体中的硫为区域各时代碳酸盐岩地层中膏盐层热化学还原作用（TSR）的产物。 |

| Abstract: | The Shaojiwan Pb-Zn deposit of Guizhou Province,China,is a medium-sized deposit of the Yadu-Mangdong metallogenic belt in the Sichuan-Yunnan-Guizhou Pb-Zn mineralization district discovered in recent years.Previous studies on geology and geochemistry of deposit were limited so that the mineral prediction and metallogenic mechanism were severely restricted.In this paper,we reported the sulfur isotope compositions of major ore minerals(Pyrite,sphalerite and galena) of primary ore body and discussed the source... |
